HYDROCYANATION OF DIOLEFINS AND ISOMERIZATION OF NONCONJUGATED 2-ALKYL-3-MONOALKENENITRILES

摘要

IMPROVED LIQUID PHASE PROCESS USEFUL IN THE HYDROCYANATION OF DIOLEFINIC COMPOUNDS TO PRODUCE NONCONJUGATED ACYCLIC NITRILES AND TO THE LIQUID PHASE PROCESS OF ISOMERIZATION OF THE NITRILES TO, AMONG OTHER THINGS, 3- AND/OR 4- MONOALKENE LINEAR NITRILES. THE IMPROVEMENT INVOLVES CONDUCTING THE PROCESS IN THE PRESENCE OF ZERO- VALENT NICKEL AND A MULTIDENTATE PHOSPHITE LIGAND. NOVEL MULTIDENTATE PHOSPHITE LIGANDS AND CATALYST PRECURSOR COMPOSITIONS MADE THEREFORM ARE ALSO DISCLOSED.
